I found this project and it seems too fun to pass up. I'm embarking on a build for my C8! I have a few Arduino Nanos with Atmega168p chipset (not the current atmega328 chipset). I think the primary difference is amount of EEPROM. Will this work or should I buy a new one?
Thanks!

Thanks Robert!
Grabbed a 328 nano, wired up the board, and everything works nicely!
Now to figure out how to connect to the C8. Seems tricky as the focuser shaft is 12.8mm, not sure how to find a shaft connector exactly that size.
Really fun project :)

Hi Alex
Sorry to inform but 168 will not work (been there done that). The code size will not fit into the space on the 168p, you will need an 328

Hi Alex
Congrats. That is really great.
For mounting ideas on SCT -

It has numerous examples from users for different types of telescopes.

If you decide to replace the focus knon with a gear, and you have a 3d printer, gears for celestron scts is found here, both for the motor and for the focus shaft
